[Dock-fans] A problem with showbox

[Leszek Dobrowolski]

Hello!
I have a problem with showbox (in the DOCK 6.1 package)
after executing

$ showbox < box.in

I get a following error:

(...)
 sphere file-
 cluster number-
fmt: end of file
apparent state: unit 1 named ./selected_spheres.sph
last format: (a80)
lately reading sequential formatted external IO
Aborted (core dumped)

My "box.in" looks like this:
Y
5
./selected_spheres.sph
1
selected_cluster_box.pdb
<empty line here>

Have you got any ideas, what's wrong with it? What is "(a80)" ?
Best regards,
Leszek
